iv4xr-demo on Lab Recruits v2.1

This new Demo version is made to align with the new Lab Recruits game version v2.1 (the similar version number is not intentional). The new version of the game has several new features such as health point and score. It also turns off the auto-fire avoidance that was problematical for iv4xr agents.
